Like the title says, my TCS and Slip lights have been staying on in my 1999 ATX nissan maxima with 106,000 km on it. Im suspecting a trany problem but can anyone verify and let me know if i shouldnt be driving it or not? My CEL has also recently come on but I think it had something to do with the 02's since they havnt been replaced yet and my O/D button used to flash but it has stopped for quite a while so i had ruled out transmission... can anyone lend me some knowledge or advice?

 

My CEL has been on for a couple of weeks now. Its a 0304 (knock sensor) and 0201 (Ignition signal primary). Every once in a while when I start the car, the TCS + SLIP light will also come on...either at time of start up or while i'm driving it'll just turn on. It doesn't come on every time though. Just once in a while. I'm not sure if its related to your problem or not........hope its not a tranny issue. Have you pulled any codes?

 

I didn't pull my ECU codes as of yet, but when I do i'll let you know what I get.

 

I have a 99 SE automatic with a similar circumstance. When the Check Engine light came on, the SLIP light also came on.

Once I pulled the codes ( knock sensor, ignition signal, & Cyl#2 misfire) and cleared the codes, the CEL and slip went out

You s/b OK once you clear the ECM

 

did you fix anything after you pulled the codes or just reset the ecm? did the slip/tcs ever come back on?

 

Reset the ECM, and replaced an ignition coil for Cyl#2.

Both the CEL and Slip lights went out

 

d_hammer, you said you had both knock sensor code and ignition signal code, did u have a bad knock sensor? Or once you replaced an ignition coil, all codes disappeared?

I need to know if having a bad ignition coil can trigger a ghost knock sensor code.

Right now I have both an ignition code and knock sensor code. But i know for a fact my knock sensor is good b/c i just replaced it and its been tested.

Haven't had time to pull ignition coils yet....too cold up here in canada. Can anyone provide a how-to to test ignition coil?

Thanks.

 

Yes all codes disappeared after the coil was replaced.

There is a test using a multmeter for the coils, and comparing the bad coil reading to the other "Good" coils. Another method is to switch the suspected bad coil to a different cylinder, and see if the misfire code also switches to that cyl.

In my case, the coil was bad intermittently. Once the code came up twice, I just replaced the coil. Just two screws and a wiring harness to change.

BTW it is -14 degrees here in Toronto today

 

d_hammer, where did u get your ignition coil from and how much? If u dont mind me asking.

 

Did anybody find the fix for this problem. It seems it could be a transmision or sensor problem. Any solutions?

 

I believe that teh TCS and Slip lights come on at the same time as the CEL, but there is no problem with the transmission. Once the CEL problem is fixed and the ECM is reset, all is well

nobel: I bought the coil from St Clair Nissan ( 3275 Dundas St W) for $158 including tax. Note that the coils on the front bank are a different item number than the rear bank ( different wiring harness configuration ). The CEL will tell you which cyl is misfiring, and which coil to replace
